Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM1 PM5 PP3 PM2_Supporting

This summary comes from the ClinGen Evidence Repository: The p.Leu189Val variant occurs in the well-characterized Forkhead functional domain of the FOXG1 gene (PM1). The p.Leu189Val variant in FOXG1 is absent from gnomAD (PM2_supporting). Computational prediction analysis tools suggests a deleterious impact; however, this information does not predict clinical significance on its own (PP3). A pathogenic missense variant (p.Leu189Phe) has been previously identified within this codon which indicates that this residue is critical to the function of the protein (PMID 28661489, GeneDx internal database)(PM5). In summary, the p.Leu189Val variant in FOXG1 is classified as likely pathogenic for a FOXG1-related disorder based on the ACMG/AMP criteria (PM1, PM2_supporting, PP3, PM5).

Genes affected

FOXG1 (HGNC:3811): (forkhead box G1) This locus encodes a member of the fork-head transcription factor family. The encoded protein, which functions as a transcriptional repressor, is highly expressed in neural tissues during brain development. Mutations at this locus have been associated with Rett syndrome and a diverse spectrum of neurodevelopmental disorders defined as part of the FOXG1 syndrome. This gene is disregulated in many types of cancer and is the target of multiple microRNAs that regulate the proliferation of tumor cells. [provided by RefSeq, Jul 2020]
